Matthew 15:2

Verse 2. Transgress the tradition of the elders, The word elders means, literally, old men. It here means the ancients, or their ancestors. Tradition means something handed down from one to another by memory: some precept or custom not commanded in the written law, but which they held themselves bound to observe. The Jews supposed that when Moses was on Mount Sinai, two sets of laws were delivered to him: one, they said, was recorded, and is that contained in the Old Testament; the other was handed down from father to son, and kept uncorrupted to their day.
